Common Emitter Amplifier, MiniPCB, 04B-005, Rev A1-04

I made a Common Emitter Amplifier with a gain of approximately 3!

1. Nitrile gloves
2. Soldering iron
3. Solder
4. Soldering wick
5. Flux
6. Isopropyl Alcohol
7. Fume extractor (with activated carbon filter)
8. Clippers
9. Tweezers

The PCB is a two layer board, and designed to be easy to manufacture and assemble. And it is optimized for cost by being panelized on 100 x 100 mm squares.

Signals are routed on the bottom layer (the layer with the part number), and a common ground plane (as uncut as possible) is on the top layer.

The P1 connector is located in a standard position with respect to the board edges: making it possible to build a universal tester, backplane, or stand.

Assemble the Resistors and Capacitors

Assemble the potentiometers (trimmers), transistor, and interface connector.

Inspect for short circuits and missing components.

Clean with isopropyl alcohol.

Test with the Digilent Analog Discovery 2/3.
